摘要： Methods of forming a polycrystalline compact using at least one metal salt as a sintering aid. Such methods may include forming a mixture of the at least one metal salt and a plurality of grains of hard material and sintering the mixture to form a hard polycrystalline material. During sintering, the metal salt may melt or react with another compound to form a liquid that acts as a lubricant to promote rearrangement and packing of the grains of hard material. The metal salt may, thus, enable formation of hard polycrystalline material having increased density, abrasion resistance, or strength. The metal salt may also act as a getter to remove impurities (e.g., catalyst material) during sintering. The methods may also be employed to form cutting elements and earth-boring tools.

摘要： A pressure pulse is initiated from the wellbore into the fractured formation where the frac fluid brings into the fractures a material that is responsive to the pressure pulse alone. Alternatively, or with a combination with a wellbore pressure pulse, well conditions such as time exposure and temperature can initiate local pressure pulses within the fracture with the result being signal generation of an electromagnetic signal that is measured with multiple sensors to allow triangulation of the location of the fracture extremities. The material can be a piezoelectric material that responds to the pressure pulse or ferromagnetic materials that similarly respond to the pulse to create the measured signals. The material can be delivered initially with the frac fluid or at different points in time during the fracture operation. Different materials with unique signal generating characteristics can be used to get a clearer picture of the extent of the fracture.

摘要： Polycrystalline compacts include a polycrystalline superabrasive material comprising a first plurality of grains of superabrasive material having a first average grain size and a second plurality of grains of superabrasive material having a second average grain size smaller than the first average grain size. The first plurality of grains is dispersed within a substantially continuous matrix of the second plurality of grains. Earth-boring tools may include a body and at least one polycrystalline compact attached thereto. Methods of forming polycrystalline compacts may include coating relatively larger grains of superabrasive material with relatively smaller grains of superabrasive material, forming a green structure comprising the coated grains, and sintering the green structure. Other methods include mixing diamond grains with a catalyst and subjecting the mixture to a pressure greater than about five gigapascals (5.0 GPa) and a temperature greater than about 1,300° C. to form a polycrystalline diamond compact.
